Outerwear Pre-Filter, 14 Round, 5 Tall, Black

OVERVIEW

When you''re tearing through the dunes or pushing your air-cooled beast through dusty trail conditions, your engine''s primary air filter is the only thing standing between a long-lasting power plant and a catastrophic top-end rebuild. The Outerwears Pre-Filter is the industry standard for off-road protection, designed specifically to wrap around your 14-inch round performance filter to provide an essential first line of defense. Engineered from a proprietary, UV-resistant polyester mesh, this pre-filter features uniform micron openings that allow for maximum airflow while stopping sand, dirt, and larger debris before they ever reach the pleats of your primary filter. By stopping the "heavy lifting" at the surface, you significantly extend the service intervals of your main filter, meaning more time on the gas and less time cleaning filters in the garage.

Beyond simple debris deflection, this Outerwears pre-filter is treated with a specialized hydrophobic water-repellent process. For the VW enthusiast running an exposed engine in a sand rail or a Baja Bug, this is a game-changer when encountering unexpected splashes or damp morning air. The water-repellent nature of the mesh causes moisture to bead and roll off rather than soaking into the primary filter element, preventing the dreaded "mud-clog" that can choke an engine and cause a rich-running condition. Whether you are running a high-performance Weber setup on a large-displacement stroker or a custom induction system on a rugged woods buggy, this black 14x5 inch pre-filter adds a professional, aggressive look while providing the technical insurance every high-performance air-cooled engine deserves.

FITMENT

This pre-filter is designed for universal application on 14-inch diameter round air filters with a 5-inch height. It is commonly used on the following air-cooled and off-road applications:

• Sand Rails & Dune Buggies: All custom builds utilizing 14-inch canister or open-element air cleaners.
• Baja Bugs: Ideal for rear-mounted exposed engines where dust kicked up by the tires is a constant threat.
• VW-Based Trikes: Provides essential protection for exposed carburetors and air intakes.
• V8-Swapped Volkswagens: Fits standard 14-inch round air cleaners commonly found on domestic engine conversions.
• Manx-Style Buggies: Perfect for street and trail builds where engine aesthetics and protection are equally important.
• Custom Off-Road Builds: Compatible with any performance filter matching the 14" x 5" dimensions.

PRO TIPS

1. Proper Cleaning for Longevity

Never toss your Outerwears pre-filter in a washing machine or use high-pressure compressed air to clean it. To maintain the integrity of the polyester mesh and the hydrophobic coating, simply remove the pre-filter and wash it by hand in a bucket of warm water mixed with a mild dish soap. Agitate it gently to loosen the dirt, rinse thoroughly with cool water, and let it air dry completely before re-installing. This ensures the micron openings stay uniform and don''t stretch out, which would compromise the filtration capability.

2. The "Snap" Test for Fitment

When installing your 14x5 pre-filter, ensure that the elastic or drawstring is seated firmly around the top and bottom plates of your air cleaner assembly. A pro-level trick is to perform a "snap test"gently pull the mesh away from the filter and let it snap back. It should stay taut. If the pre-filter is sagging or loose, it can flap at high speeds or under high intake vacuum, which can eventually lead to wear holes where the mesh rubs against the wire backing of your primary filter.

3. Monitoring the Hydrophobic Coating

While the water-repellent treatment is incredibly durable, it is not permanent and can wear down after many wash cycles or extreme exposure to harsh solvents. To test if your pre-filter is still repelling water effectively, simply flick a few drops of clean water onto the surface. If the water beads up and rolls off immediately, you are good to go. If the water begins to soak into the mesh, it is time to replace the Outerwears to ensure your engine stays protected during those damp morning sessions or wet trail rides.
